Information on using Radiance® to model Solera.
Overview:
As Solera is a relatively new product, it is not yet installed in the default libraries of Desktop Radiance 1.02. As well, there is also no glazing editor available in this version of Desktop Radiance. Despite this, it is possible to include Solera in your own Desktop Radiance renderings. The process we will use involves the borrowing of an existing Radiance glazing attachment and replacing its contents with the parameters for Solera. The simulation is then run with that attachment. The resulting images and data will be calculated using Solera translucent glazing.
Please Note:
The following instructions are based upon the assumption that the operator is experienced in the use of Radiance and is fluent with Radiance terminology.
Process:
- Download from this site the zip archive (Solera Data Files.zip) provided. This archive has data files which Radiance will use to model Solera. Included are files for Solera units with 20%, 30%, 40%, 50%, 60% and 70% visible light transmittance. (Solera can be manufactured with virtually any light transmittance up to 73%. Should you require a more precise match, our technical services group can provide you with a custom file.)
- You will need to identify a Radiance glazing attachment that you will be borrowing to use later as the host for the Solera parameters. We recommend using AFG GP308 as the Solera files have been created to replace the contents of that particular attachment without modification. You don't need to do anything at this time with the chosen glazing attachment. (You may chose a glazing attachment other than AFG GP308 but this will involve additional work on your part).
- Create your model. Attach the borrowed glazing where you want to attach Solera. Once your model is complete and all attachments have been made, begin a simulation as usual, choosing appropriate options for camera, reference grid or reference point.
Note: Do not hit the start button when the simulation setup box appears. Before you start you will have to replace the data file for AFG GP308 glass with one for Solera.
 Without closing the model, find the database folder for this model. You may have been prompted for a location by a message like this one.
In it you should find a subfolder named "glz". Inside this folder there should be one named "afg". That folder will contain data files for all of the AFG glazings in your model. One of these files should be named "Gp308.rad". It is the contents of this file that you will be replacing. The downloaded zip archive contains separate folders for each Solera light transmittance level. Choose the folder which has the closest to your desired light transmittance. Copy the appropriate file, also named GP308.rad, and replace the original Gp308.rad found in the \glz\afg\ folder.
- Now you can go back to the simulation setup box and choose your date, time, etc and start your simulation as normal.
For the Future:
As long as you do not move or replace this model's database you should not have to repeat this procedure for different simulations of this model.
